What is the IIAS?

There are currently over 31,000 national, regional, and local merchants using the Inventory Information Approval System (IIAS). When a participant swipes the Flex Card at a participating merchant, the system automatically validates eligible items purchased at the point of sale, and requires an alternate method of payment for ineligible items purchased at the same time. Consequently, further documentation is not needed from the participant for these transactions. This is great news for participants and makes the Flex Card even more convenient and easy to use.

IIAS Store Locator New! Use this locator to find IIAS merchants close to you. Note: The Store Locator allows you to search for IIAS merchants, 90% merchants, or both. Be sure to select only IIAS merchants, unless you know for sure that your plan allows the Flex Card to work at 90% merchants. If you are unsure, please contact ProBenefits.

Please Note:

Due to IRS regulations, the Flex Card does not work at retail merchants without the IIAS in place. You can use the list above to see if your favorite retail location is currently participating or has plans to participate. Check the Planned Merchant Implementation Date column: "Live" indicates that the merchant has the IIAS in place, a date indicates the expected date for IIAS participation, and TBD indicates that the merchant is currently working on implementing the system but does not yet have an expected date of completion.

Although Costco Wholesale is included on this list, the Flex Card will not work there because they do not accept Master Card credit cards. The Flex Card will work at Costco.com.
